Applications
The 800G QSFP-DD QDD DR8 Optical Transceiver is used in 800G Ethernet data center and cloud network environments, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 500m. The MTP/MPO-16 APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Juniper Networks hardware, it is a drop-in equivalent of the QDD-2X400G-DR4. The link runs 8x 106.25Gb/s PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA HW Rev 6.01, CMIS 5.0, IEEE 802.3cu, IEEE P802.3ck. For projects standardized on Juniper Networks hardware, this product replaces the QDD-2X400G-DR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
To order, quote QDD-DR8-800G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
